• Generic Silicone Air Fryer — biggest strength: one food-grade silicone pan with 3 cavities, non-stick release, dishwasher-safe cleaning, and the widest appliance range here (air fryer, oven, microwave, refrigerator, hamburger steamer).
• Generic Silicone Air Fryer — biggest trade-off: it's a single pan, so you're working in one batch, and at 1.3 x 8.43 x 1.3 inches it's a long, flat shape that won't stack into a tight drawer.
• WJIAAA 4PCS — biggest strength: four separate 3.94 in diameter x 1.18 in deep round molds, so you can portion several burgers or buns at once and stack them to save storage space.
• WJIAAA 4PCS — biggest trade-off: no microwave or refrigerator use is stated, and the smaller diameter means less room per cavity for layered recipes.
• Who each pick is for: Generic is for the cook who wants one do-everything mold; WJIAAA 4PCS is for the cook who wants round, uniform burger buns in quantity.
This is the flexible all-rounder of the two. It's a single food-grade silicone pan with three cavities, and the design brief is clearly "make eggs and small baked goods without babysitting them." The non-stick surface means food lifts out without a spatula, and cleanup is a rinse with mild soap or a trip through the dishwasher. For someone who air-fries hamburger patties and wants a bun-shaped mold for the bread side of the sandwich, that non-stick release matters — you don't want to pry a soft bun out of a cavity and tear it.
Where it separates from the WJIAAA set is appliance range. The spec sheet lists air fryer, oven, microwave, refrigerator and hamburger steamer. That's a genuinely wide net: mix batter in it, chill it in the fridge, bake it in the oven, reheat in the microwave. The silicone is described as flexible and smooth, resistant to deforming or breaking, so it survives being bent to release food and then washed.
At just 3.52 ounces and 1.3 inches tall, it's thin and light. The 8.43-inch length is the number to think about — it's a long pan, so check your air fryer basket width before you commit. It comes in pink.
Skip it if you regularly cook for a crowd, want true round buns in quantity, or need something that stacks flat in a cramped cabinet.
WJIAAA 4PCS: Who It's For
The WJIAAA set takes the opposite approach: instead of one pan with three cavities, you get four individual round molds, each 3.94 inches across and 1.18 inches deep. Four separate pieces means four independent portions. You can pull one out of the air fryer while the other three keep cooking, or run two in the air fryer and two in the oven at the same time — the spec sheet explicitly calls out dual-appliance use for simultaneous batch cooking.
The 1.18-inch depth is the detail that matters for burgers. It's deep enough to hold a layered recipe — the description mentions lasagna cups and mini meatloaves alongside the obvious pancake, English muffin and burger bun uses. Meanwhile the 3.94-inch diameter gives you a neat, consistent circle, which is exactly what you want if the goal is a bun that matches the patty instead of a lopsided blob.
Release works the same way as the Generic pan: polished non-stick surface, food comes out intact with a gentle push. The brand does recommend lightly oiling the mold before adding batter or eggs for the best result. Cleaning is dishwasher-safe or a soapy-water rinse, and because the four molds are flexible they stack — the spec sheet claims around 70% storage savings versus rigid pans, which adds up in a small kitchen.
At 5.44 ounces for the set, and pink, it's still light. The trade-off is scope: no microwave or refrigerator use is stated, and the smaller diameter limits how much you can load per cavity.
Buy it if you want several round buns or egg portions at once, you cook across two appliances simultaneously, or storage space is tight.
Skip it if you want one compact unit, need microwave or fridge-to-oven flexibility, or prefer a single pan to keep track of.
• Best for hamburger bun shaping → WJIAAA 4PCS. Four 3.94-inch round molds produce uniform circles that match a patty, versus the Generic pan's elongated 3-cavity layout.
• Best for appliance versatility → Generic Silicone Air Fryer. Air fryer, oven, microwave, refrigerator and hamburger steamer are all listed; WJIAAA states air fryer and oven only.
• Best for cooking several portions at once → WJIAAA 4PCS. Four separate molds can be split between appliances or across batches.
• Best for storage in a small kitchen → WJIAAA 4PCS. The flexible molds stack compactly; the Generic pan's 8.43-inch length is harder to tuck away.
• Best for the fewest pieces to wash → Generic Silicone Air Fryer. One pan, three cavities, dishwasher safe.
• Best for deeper, layered recipes → WJIAAA 4PCS. A stated 1.18-inch depth accommodates stacked recipes like lasagna cups.
• Best for someone who wants one tool for everything → Generic Silicone Air Fryer. It's the broader, more forgiving pick if you'd rather not manage four separate molds.
• Best for anyone unsure → check the current price on Amazon for both and let your cooking volume decide. If you fry two patties at a time, Generic is plenty. If you're feeding four, WJIAAA wins.
In my opinion, WJIAAA 4PCS is the better buy for anyone whose main goal is air fryer hamburgers. Four round 3.94-inch molds give you uniform buns and the freedom to work in batches across the air fryer and oven, and the stacking design means the extra pieces don't cost you cabinet space. I'd pick the Generic Silicone Air Fryer instead if you want a single mold that also handles microwave and fridge duty — but for burger-night volume and round, even buns, WJIAAA is the one I'd reach for.
FAQ
how to air fryer hamburgers
Shape your patties and, if you want a matching bun, press the dough or batter into a round silicone mold — the WJIAAA 4PCS molds at 3.94 inches are sized for that. Cook the patties in the air fryer basket and the buns in the mold, then assemble. Both molds here are non-stick, so food releases with a gentle push.
Form even patties so they cook at the same rate, and give them space in the basket rather than crowding them. If you're using either silicone mold for a bun or egg to go alongside, note the WJIAAA set is designed for air fryer and oven use, while the Generic pan also lists microwave and refrigerator.
how to air fry hamburgers from frozen
Frozen patties need longer and benefit from a flip partway through so they brown evenly. Keep the bun or egg mold separate from the raw patties — both products are food-grade silicone and dishwasher safe, so a quick wash between uses is straightforward.
how long to air fryer hamburgers
Timing depends on patty thickness and your air fryer, so go by doneness rather than a fixed number and check the center. The molds themselves are rated for high temperatures and are flexible and durable, so they hold up to repeated air fryer and oven cycles.
